Jefferson
Lab requires that Visitor(s)
entering non-public[1]
areas be accompanied by an Escort. Before entering non-public areas,
Escorts are responsible for ensuring their Visitor(s) has a basic understanding
of the hazards that may be encountered during the visit. This
document provides safety topics to be discussed and actions to be performed
prior to entering a non-public area with the Visitor(s)

This
appendix provides information to be included in a Visitor’s safety briefing. Additional
information can be provided as necessary at the discretion of the Escort. Review
the ES&H Manual
for additional, or more detailed, processes and procedures.

Jefferson Lab considers no activity to be so urgent or important that
we will compromise our standards for environmental protection, safety, or health.
Escorts provide an initial safety briefing, which includes the Basic Safety
Information outlined below, to Visitor(s)
with the minimal expectation that this goal will be achieved.

In all situations the first response of a Visitor(s) is to follow their Escort’s
instructions.

At
Jefferson Lab there are a variety of built-in safeguards to alert individuals
to a potentially dangerous situation. Evacuation is the most common activity
performed when an alarm is activated. Visitor(s) are to follow their Escort’s
directions and proceed to the designated muster point.

Escort Actions:

·Review
the emergency exit locations and appropriate muster point with your Visitor(s).
(Exits are clearly marked by lighted signs in hallways and above exit doors. Evacuation
floor plans are posted conspicuously in buildings.)

Visitors are asked to resist the urge to
touch…anything. Aside from the fact that an experiment may be jeopardized, or
equipment damaged – specific hazards to people include: pinch, cuts, shock, and
blindness.

Escort Actions:

·Do not allow your
Visitor(s) to touch or handle any apparatus, equipment,
or material unless you have given them specific permission to do so.

Though Jefferson Lab has unusual equipment and complex activities,
the most likely hazards are slips and trips. Uneven walking surfaces are
generally the major culprit.

Escort Actions:

·Tell Visitors to watch their step.

·Point out trip/slip hazards when encountered.

·Use designated walkways.

·Hold hand railings wherever possible.

·Tell your Visitor(s) to ask for
assistance, if they need it, to maneuver around obstacles.

·Adjust your route to accommodate inappropriate
footwear. (High heels and sandals are not recommended anywhere on site, and are
not allowed in some areas. Communicate this to your Visitor(s) prior to their
arrival.)

Everyone at
Jefferson Lab has the right to know the hazards which they may be exposed.Escorts are required to
describe the foreseeable hazards that may be encounter, to their Visitor(s) and
perform the associated actions to facilitate their safety.

ODH means not having an adequate amount of oxygen to breathe and
could occur if cryogens, or other chemicals or gases, are released. Such
a release could quickly reduce oxygen levels in an area. Only trained,
certified, and qualified individuals are allowed to enter ODH-rated areas without an Escort.

Cryogens are used at Jefferson Lab. Hazard issues include thermal cold
(immediate tissue damage) and Oxygen Deficiency. Buildings and work
areas where cryogens are used are posted with warning signs. Only individuals
who are trained, qualified, and authorized are allowed to work with cryogens at
Jefferson Lab. Appropriate PPE is worn when working with these materials.

Escort Actions:

·Don appropriate PPE.

·Tell
your Visitor(s) to
remain clear of cryogenic liquids during handling or dispensing.

Jefferson Lab has a few areas
where magnetic fields or RF radiation could interfere with instruments and
electronic apparatus, including bioelectronic
devices
such as cardiac pacemakers.

Posted signs and flashing red
warning lights indicate the presence of high magnetic fields in specific areas.
In most cases, tape/rope or blockades indicate the potential “reach” of these
magnetic fields.

Escort
Actions:

·Ask
your Visitor(s) if they are affected by these limitations and alter your route
to accommodate them.

Jefferson
Lab’s accelerators and some components produce ionizing radiation, mostly
x-rays, during operation. Radiologically
controlled areas are posted with signs and, in
some cases, warning lights. People under age 18 are not allowed to enter these
areas.Jefferson Lab does not recommend
that women who are pregnant enter these areas.
